Simon: You need me to look at that?
Mal: Just a graze.
Simon: So, where do you plan on dumping us?
Mal: There’s places you might be safe. You want the truth, though, you’re probably safer on the move. And we never stop moving.
Simon: I’m confused. No wait, I — I think maybe you’re confused.
Mal: It may have become apparent to you that the ship could use a medic. You ain’t weak. I don’t know how bright you are, top three percent, but you ain’t weak and that’s not nothing. You live by my rule, you keep your sister from doing anything crazy, you could maybe find a place here. ‘Til you find a better.
Simon: I’m trying to put this as delicately as I can… How do I know you won’t kill me in my sleep?
Mal: You don’t know me, son. So let me explain this to you once: If I ever kill you, you’ll be awake, you’ll be facing me, and you’ll be armed.
Simon: Are you always this sentimental?
Mal: Had a good day.
Simon: You had the Alliance on you, criminals and savages… half the people on the ship have been shot or wounded including yourself, and you’re harboring known fugitives.
Mal: We’re still flying.
Simon: That’s not much.
Mal: It’s enough.
